Abstract
The invention relates to a wide-temperature-range high-frequency low-loss magnetic material. The basic formula of the material comprises ferric oxide, manganous-manganic oxide and zinc oxide, and on the basis, a plurality of additives are added. A preparing technology of the wide-temperature-range high-frequency low-loss magnetic material includes the steps that detection analysis is carried out, the materials are mixed and subjected to procedures of vibration grinding, piece rolling, shaping, pre-sintering, coarse smashing, fine smashing, pulping, formula analysis and adjustment, spraying prilling and the like, and powder is prepared; a corresponding ferrite magnetic core is manufactured with qualified materials, wherein the main technological procedures for manufacturing the magnetic core include powder wetting, forming, sintering, grinding, cleaning, separate measuring and packaging. Compared with the prior art, the wide-temperature-range high-frequency low-loss magnetic material and the preparing technology have the advantages that the initial magnetic permeability of the obtained material is low, the loss rate of the magnetic core is low, dropping of the initial magnetic permeability mu<i> is low, and the requirement that the soft magnetic material has the better wide temperature characteristic and the high-frequency low-power-loss characteristics is achieved.
Description
Technical field
The present invention relates to a kind of wide temperature high frequency low loss magnetic materials.
The present invention relates to the preparation technology of a kind of wide temperature high frequency low loss magnetic materials.
Background technology
At present, the development trend of electronic communications network (ECN) especially mobile network's high frequency is the most fast
Suddenly, due to increase and the raising of technology of function, to its power supply soft magnetic ferrite
Characteristic requirements is had higher requirement, and i.e. requires that soft magnetic materials possesses the widest temperature characteristics
Characteristic with high-frequency low-power loss, it is desirable to properties of materials index reaches: initial magnetic permeability:
